摘要： A method of and apparatus for making, and the resulting material for fabricating reclosable bags and in which a length of web of predetermined width of bag material as wound on a mandrel has fastener strip sections joined to and across the width of the web. The web is adapted to travel continuously spirally about the mandrel. The fastener carrying web may be folded longitudinally and resiliently flexible profiles of the folded fastener strip sections separably joined. Ends of the fastener strips before, and after, folding may be flow melted and fusedly flattened. Ends of the fastener strips may be aligned with a fold juncture of an underturned flange of the web and the margin then unfolded to extend beyond the strip ends.

摘要： A method for producing an oriented plastic strap having a predetermined desired thickness for use in strapping packages and the like is passed between a pair of cylinders or rollers placed closely together at a desired nip for reducing the thickness of the sheet. One roller is rotated at a faster lineal rate of speed than the other, and the rollers rotate in opposite directions. This method achieves milling and stretching of the material substantially simultaneously at the nip of the rollers.

摘要： A machine for fastening one or more layers of roofing material to an underlayment, and a stackable washer therefor. A chute receives a stack of such washers. A shuttle displaces a single washer to a separated position when moved in one direction, to which the shuttle is biased, and releases the single washer when moved in the opposite direction. A gate, which cooperates with camming surfaces defined upon the respective washers, restrains the overlying washer within the stack against being displaced along with the single washer and restrains the single washer from being displaced from the separated position. Various components are provided by linking a stand-up screw gun of a known type to the shuttle. The stackable washer is embossed so that each such washer and like overlying and underlying washers within a stack contact each other at three or more places, which define tangent planes intersecting planes defined by planar areas upon such washers at angles greater than 45.degree. but less than 90.degree. whereby such washers are spaced from each other around their entire peripheries. Notches defined within the washers cooperate with ribs provided within the chute so as to ensure that a stack of the washers is oriented properly when disposed within the chute.
